Description
The invention relates to a sound-absorbing floor, in particular for ships, according to the preamble of claim 1. A floor of the generic type, the sole purpose of which is to meet fire protection requirements, is known from DE 202 06 230 U1. Here, support pipes with an internal thread are secured to a base plate by welding, with a vertically adjustable threaded bolt being arranged in each of said pipes. This threaded bolt carries a head plate, which is vertically adjustable together with the threaded bolt. On this head plate, a bottom plate is arranged, which has a lower covering configured as a fire protection plate. The sole purpose of this embodiment is to provide fire protection.
In passenger ships and yachts, there are more and more restrictions in terms of a maximum sound level to be observed. Attempts have been made to meet these requirements by providing oscillating elements including rubber mountings underneath the actual flooring. On the other hand, however, there is the general rule in shipbuilding that no flammable materials must be used behind coverings.
Therefore, it is the objective of the invention to provide a sound-absorbing flooring, in particular for ships, which is able to meet high sound absorption and fire protection standards.
This objective is attained according to the invention by the features in the characterizing part of claim 1.. On the one hand, an inherently rigid substructure is provided as support, which allows uneven areas of the deck or the like to be levelled out. The actual sound absorption then occurs in the floor panels disposed on the substructure.
The sub-claims include a number of advantageous and inventive further developments of the solution according to the invention.
Further details, advantages and features of the invention will be apparent from the ensuing description of an exemplary embodiment of the invention, taken in conjunction with the drawing, in which
Fig. 1 shows a sectional view of a bolt fastened to a deck, the bolt comprising a head holder forming part of a substructure,
Fig. 2 shows a view corresponding to Fig. 1 with a support rail fastened to the head holder,
Fig. 3 shows a longitudinal sectional view of a floor panel with groove and tongue,
Fig. 4 shows a longitudinal sectional view of a floor panel provided only with a tongue,
Fig. 5 shows a longitudinal sectional view of a floor panel provided only with a groove,
Fig. 6 shows a view corresponding to Fig. 2 with installed floor panel and an upper cover plate,
Fig. 7 shows a view corresponding to Fig. 6 rotated by 90°, and
Fig. 8 shows a plan view of a laid flooring without cover plate.
On a lower floor, for instance a deck 1 of a ship, bolts 2 are fastened in a vertical direction by means of a weld seam 3. At their upper end, the bolts 2 are provided with an external thread 4 to which a head holder 5 is screwed. A head holder 5 of this type comprises a sleeve 6 with an internal thread 7 adapted to the external thread 4 and an upper circular head plate 9 extending perpendicular to the common axis 8 of bolt 2 and sleeve 6. All head holders 5 installed for a flooring are screwed on the respective bolt 2 in such a way that the upper sides of the head plate 9 lie in a common plane. As can be seen from Fig. 8, bolts 2 are in each case arranged in a straight row (horizontal in Fig. 8) such that a respective support rail 10 can be placed on each row of head holders 5. The bolts 2, which are in each case arranged in one row at the same distance a from each other, of adjacent rows are staggered in relation to each other by half said distance, in other words a/2, as can be seen from Fig. 8 as well. The support rails 10 are in each case secured to the head holders 5 by means of an adhesive layer 11 and, furthermore, by means of rivets 12. The purpose of the rivets 12 is to prevent the support rails 10 from sliding in relation to the head plate 9 during the mounting thereof, and to secure the support rail 10 to the head plate 9 until the adhesive layer has cured. The adhesive layer 11 forms at the same time a non-positive connection and a chemical separation between the different materials of the head plate 9, namely steel, and of the support rail 10, namely aluminum, and, furthermore, is to prevent creaking sounds produced by small movements between the support rail 10 and the head plate 9.
The support rails 10 have a hat profile, in other words they have a downwardly open C-profile with laterally adjoining flanges 14. As a result, an extremely warpresistant support rail 10 is obtained. Furthermore, the flanges 14 can be used as support for end rails 10’, serving as cross-bracings, arranged in the edge region between adjacent support rails 10 if cross-bracings of this type should be necessary.
The actual sound-absorbing flooring 16 is installed on the substructure 15 formed by the bolts 2, the head holders 5, the support rail 10 and the end rails 10’. Said flooring 16 consists of floor panels comprising a lower half-shell 18 and an upper half-shell 19 between which a sound-absorbing core 20 of mineral wool is arranged. The half-shells 18,19 consist of steel or aluminum sheet metal. They are connected to each other substantially not directly, thus avoiding the formation of acoustic bridges. The elongate floor panels 17 configured in a rectangular shape with long sides 21 and short sides 22 are provided with a tongue 23 on one end, in other words a short side 22, and a groove 24 on the opposite short side 22, thus allowing them to be interconnected by plugging. In the groove 24, a C- shaped reinforcing member 25 is inserted. The short sides 22 of the floor panels 17 are partly covered by the half shells 18, 19, as can be seen from Figs. 3 to 5.
Corresponding to the installation, the floor panels 17’ or 17” arranged at an outer edge (see upper and lower sides of Fig. 8) of the flooring 16 only have a tongue 23 and no groove 24 (Fig. 4) or only a groove 24 and no tongue 23 (Fig. 5).
Finally, a cover plate 26 is arranged on top of the installed floor panels 17, 17’, 17”, which cover plate 26 may consist of aluminum, steel or a composite material. A cover plate 26 of this type is fastened to the floor panels 17, 17’ by means of an adhesive layer 27. If a cover plate 26 of this type is made of a screed, the adhesive layer can naturally be omitted. The cover plate 26 ensures an improved distribution of pressure.
